Sažetak
An universal and inexpensive inductive voltage correction method for winding resistance measurement has been analyzed. This method enables winding temeperature rise determination by change of its resistance even in the larges transformers, despite of long-lasting transient phenomenon of DC measuring current. Errors have been analyzed in detail. Due to the increased temperature rise determination error, the correction method should be used only when the transient effects cannot be reduced by the increase of DC measuring source voltage to duration shorter than 2 min.
